This probably doesn't help you out of your problem: We saw strange effects when WRITING from a Linux machine (also around Suse 6.4, don't remember which Kernel, libc and nfsd versions) onto an nfs mounted disk exported by an AIX (4.3.x) computer. We came across it when we recompiled programs known to work and then tried to run them. We got SIGSEGVs. When telling the compiler to write the executable into /tmp (on the local Linux machine), the program ran without problem. Comparing the two different executables (I remember that they had the same size), showed that 'somebody' inserted 0 zero bytes after 8192 bytes and similar things. (The effect was reproducible). However, your case seems to be in the opposite direction (for which I remember that we never saw problems). best regards, André -- ------------------+---------------------------------- Andre Holzner | +41 22 76 76750 Bureau 32 2-C13 | Building 32 CERN | Office 2-C13 CH-1211 Geneve 23 | http://wwweth.cern.ch/~holzner/
